ABB SACE Tmax circuit breakers

Circuit breakers of the new Tmax series from ABB Group are designed for complete solutions. They are of the best standard performance, combined with ease of selection and installation. Switching technology of the latest generation allows you to combine protective releases with data exchange units in one package. With Tmax, you have everything at hand — all kinds of accessories and connection terminals. The Tmax series expands your freedom of action!

It was not easy to find solutions that would allow circuit breakers to achieve such a high level of performance with a low level of dimensions. But thanks to the experience gained over decades by such a leader as Concern of ABB, the goals were achieved. Namely, small-sized automatic switches T1, T2, T3, T4, T5, T6, T7. All switches are equipped with new arc chutes that reduce arc extinguishing time. All T1 switches are double insulated for added security.

From the beginning, the possibility of cooperation Tmax T1, T2 and T3 switches was considered, a single range of accessory switches was created.You can choose functions and features that are up-to-date and cannot be found on circuit breakers of this size. Excellent performance up to 250 A. These three sizes have many characteristics in common and a single implementation in depth (70 mm) of three device types greatly simplifies installation.

Tmax T1

Thanks to its compact dimensions, the Tmax T1 circuit breaker is unique in its class. Compared to any other circuit breaker with similar characteristics (160 A — 36 kA at 415 V alternating current), the overall dimensions of the device are much smaller (width — 76.2 mm, height — 130 mm, depth — 70 mm) . In addition to mounting on a mounting plate, T1 switches can also be mounted on a DIN rail. Produced in 3 and 4-pole version for currents from 16 to 160 A with characteristics (B- 16 kA, C- 25 kA, N — 36 kA). All circuit breakers of the Tmax T1 series are equipped with thermomagnetic releases (TMD) — adjustable thermal threshold (0.7 to 1 In), electromagnetic threshold is fixed (10 In). The circuit breaker T1 can be operated manually or by means of an electromagnetic drive.

Tmax T3
First reduced size 250 A circuit breaker compared to any other similar equipment (width — 105 mm, height — 150 mm, depth 70 mm), which allows easy installation of automatic circuit breakers for currents up to 250 A in standard panels. In fact, it allows you to significantly facilitate the design, assembly and installation phase of electrical structures. Provides breaking capacity of 50 kA at 415 VAC. They are produced in 3- and 4-pole versions for currents from 63 to 250 A with characteristics (N — 36 kA, S — 50 kA).
The circuit breaker T3 can be operated manually or by means of an electromagnetic drive. T3 can also protect the electric motor when equipped with suitable accessories.

Tmax T4
320 Molded-case circuit breaker with sufficiently small dimensions compared to other similar equipment (width — 105 mm, height — 209 mm, depth — 103.5 mm). Switches of this size are manufactured in stationary, recessed and pull-out designs. Chain breakers the retractable version can be rolled out with the compartment door closed, thus increasing operator safety. The circuit breaker is operated either manually or motor operated. Exclusion is provided. capacity 70 kA at 415 VAC.Available in 3 and 4 pole design for currents from 20 to 320 A with characteristics (N — 16 kA, S — 25 kA, H — 36 kA, L — 50 kA, V — 70 kA).
Tmax T4 circuit breakers can (provided that some accessories) provide a selective zone, can work in the protective circuit of electric motors, and are also used as switch disconnectors.

Tmax T5
630 Molded case circuit breaker with small (width — 139.5 mm, height — 209 mm, depth — 103.5 mm) dimensions. T5 switches are produced in stationary versions, with plug-in and pull-out, and with control of the switch performed both manually and by means of a motor drive. Provides breaking capacity of 70 kA at 415 VAC. They are produced in 3- and 4-pole versions for currents from 20 to 320 A.

Tmax T6
1000 Molded Case Circuit Breaker (Width 210mm, Height 273mm, Depth 103.5mm). Switches are produced in stationary and pull-out versions. The breaker is operated both manually and with the help of a motor drive. Provides breaking capacity of 70 kA at 415 V AC. They are produced in 3- and 4-pole versions for currents from 20 to 320 A with characteristics (N — 16 kA, S — 20 kA, H — 36 kA, L — 50 kA). Tmax T6 equipped with thermomagnetic release (TMA), thermal threshold adjustable (0.7 to 1 In), electromagnetic threshold adjustable 5 to 10 In; adjustable magnetic release (MA); electronic release of protection. Tmax T6 circuit breakers can, subject to the installation of certain accessories to ensure a selective zone, and operation in the protective circuit of electric motors, can be used as switch disconnectors.

Tmax T7
1600 Circuit breaker with molded case (width — 278 mm, height — 343 mm, depth 251 mm).Switches of this size are manufactured in stationary and pull-out designs. The circuit breaker is operated either manually or motor operated. Exclusion is provided. capacity 60 kA at 415 VAC. It is available in 3 and 4 pole versions for currents from 200 to 1600 A.
T7 can be mounted both horizontally and vertically; all types of leads are available (including flat rear oriented wires) and a new, faster and safer moving part unfolding system. What's more, thanks to the reduced height, it greatly simplifies the routing of cables. An innovation is a system for quick installation of accessories: no wires inside the automatic switch, fast, simple and reliable connection to an external circuit, no screws for attaching external power cables.

The new cable locking system provides undeniable advantages in terms of optimal size. Thanks to this, the system can lock two circuit breakers in any position and, most importantly, lock the T7 circuit breaker with an air circuit breaker switch. This previously thought-to-be-impossible solution is ideal for realizing automatic switching without power interruption.

Double insulation
The design of the switches provides double isolation between the lower part of the voltage from the power parts (excluding the terminals) and the front part of the apparatus, until touched by the operator during normal operation of the installation. Socket for each electrical accessory is completely separated from the power circuit, preventing any risk of contact with live elements. In particular, the control mechanism is completely isolated from live elements.

In addition, the circuit breaker has thickened insulation both between internal live parts and between terminals. In fact, the insulation distances exceed those specified in the standards. IEC and meet the requirements of UL 489 (USA).

Direct breaker control
The control lever always shows the exact position of the moving circuit breaker contacts and guarantees a reliable and reliable indication in accordance with the guidelines of standards IEC 60073 and IEC 60417-2 (I — closed; O — open; yellow-green line — open due to protective operation ). The circuit breaker control mechanism is equipped with an autonomous release that works regardless of the force and speed of the lever to perform the operation. When the protection is triggered, the moving contacts automatically open. To close them again, the control mechanism must be raised. again by moving the control lever from the intermediate to the extreme lower position.
