ABB Tmax T7 series molded case circuit breaker

ABB Tmax T7 series molded case circuit breaker

Product Overview

Series positioning: The Tmax T7 series is a high current model in ABB molded case circuit breakers, covering a current range of 630A-2500A, designed to meet the needs of high reliability, high breaking capacity, and compact design in industrial distribution systems.

Product types: including distribution circuit breakers (with thermal magnetic or electronic release), motor protection circuit breakers, etc., suitable types can be selected according to different application scenarios.

Core technical parameters and performance

Breaking capacity: At 480V AC voltage, the breaking capacity can reach 150kA, which can effectively deal with short-circuit faults and ensure system safety.

Release type:

Thermomagnetic release: Provides overload and short circuit protection, with relatively fixed parameter settings, suitable for conventional protection scenarios.

Electronic release devices (such as PR231/P, PR232/P, etc.): have more precise protection functions, support multiple protection curves, and can provide precise protection against overload, short circuit, grounding faults, etc. Some models also support communication functions (such as Modbus RTU), making remote monitoring and management easier.

General parameters: protection level IP54, insulation level F, temperature rise level B (some models are F), operating temperature range -25 ℃ to+70 ℃, storage temperature -40 ℃ to+70 ℃, in compliance with multiple international standards such as IEC 60947-2.

Installation and Configuration

Installation method: Supports fixed installation, plug-in installation, and pull-out installation. Multiple installation methods can meet different cabinet design and maintenance needs. Some models can be converted to different installation methods through conversion kits.

Connection method: Provides multiple terminal types, including front wiring, rear wiring, multi cable terminals, etc., suitable for copper and aluminum cables, making it easy to connect with different lines.

Accessories: Equipped with a variety of accessories such as auxiliary contacts, undervoltage release, shunt release, remote control mechanism, residual current release, etc., the circuit breaker function can be expanded according to actual needs.

Application and Authentication

Application scenarios: Widely used in industrial power distribution systems, large building power distribution, energy industries, and other fields, it can be used for main power distribution, feeder line protection, and protection of large motors.

Certification: Compliant with multiple international standards such as UL 489, CSA C22.2, IEC, and some models have been certified by classification societies (such as ABS, RINA, etc.) to ensure the applicability of the product in different regions and industries.
