ABB 2TFB100381R1001 Moulded Case Circuit Breaker - Tmax T
Part Number: 2TFB100381R1001
Quick Summary
ABB 2TFB100381R1001 is a moulded-case circuit breaker for reliable low-voltage protection in industrial control panels. Engineers often face tight spaces, complex wiring, and regulatory pressures that slow time-to-protection. This device supports RoHS compliance, REACH declarations, and CMRT traceability, strengthening supply-chain responsibility. With Tmax T generation technology and a 4P DC configuration, it offers predictable tripping and fast isolation. For panel builders and integrators, this translates to easier installation, improved compliance metrics, and reduced lifecycle costs. Designed for 4P DC protection, it's compatible with ABB SACE Tmax T accessories and standard DIN rail mounting. Beyond protection, it supports regulatory and environmental data sharing through included documentation such as REACH, RoHS, and CMRT files.

FAQs
Install the MCCB on a standard DIN rail in a protected enclosure, ensuring proper clearance for heat dissipation. Mount on a compatible busbar and connect the four poles with correctly rated conductors. Torque connections per the datasheet and verify the DC tripping characteristic matches the protection scheme. Use the Tmax T accessories recommended by ABB to maintain clearance and ensure safe, reliable operation.
The device is a 4P DC moulded-case circuit breaker from the SACE Tmax T family, designed for low-voltage protection with current ratings from 250 A up to 1600 A. It features four poles, DC protection capability, and is part of ABB’s Tmax T generation. It also carries RoHS and REACH declarations and CMRT traceability for compliance and supply-chain transparency.
Yes. The product carries RoHS information and a RoHS declaration, aligns with EU Directive 2011/65/EU and 2015/863, and includes REACH declarations. CMRT is also provided, supporting conflict-mineral reporting and supply-chain transparency, which helps with regulatory compliance and responsible sourcing.
This 4P DC MCCB is well-suited for industrial control panels, motor drive cabinets, DC distribution, and plant automation circuits. It enables selective tripping in DC networks, supports modular panel designs, and simplifies integration with standard DIN rail systems. It also aligns with sustainability reporting and environmental documentation requirements for industrial facilities.
Maintenance is primarily visual and periodic electrical checks of mounting, wiring, and insulation integrity. The MCCB’s robust Tmax T design reduces nuisance trips and provides predictable performance, contributing to lower downtime and improved uptime metrics. With CMRT, RoHS, and REACH compliance, procurement risk and regulatory overhead are reduced, supporting a lower total cost of ownership over the panel’s life cycle.
