ABB SACE FORMULA A1A 125 TMF 80-800 4P 1SDA066532R1 integrates thermomagnetic TMF trip unit, provides thermal overload protection and instantaneous magnetic short-circuit protection for AC and DC low voltage distribution circuits. This ABB SACE FORMULA A1A 125 TMF 80-800 4P 1SDA066532R1 is widely stocked as spare branch protection unit for power distribution assemblies.

Features

ABB SACE FORMULA A1A 125 TMF 80-800 4P 1SDA066532R1 adopts fixed thermal magnetic release, thermal setting matches 80A rated current, magnetic instantaneous trip threshold fixed at 800A. The breaker uses front terminal connection, supports manual local ON OFF operation and clear trip status indicator window. This 4-pole design includes protected neutral pole, suitable for three-phase four-wire power distribution system. It supports optional accessories including auxiliary contact, alarm contact, shunt trip release and undervoltage release for remote control and fault signal transmission to PLC and monitoring system. The unit complies with IEC 60947-2 standard, CE and other global certifications. It is designed for 24/7 continuous operation in industrial low voltage switchboards, pump control cabinets, factory power distribution panels and commercial power supply systems.

Principle

ABB SACE FORMULA A1A 125 TMF 80-800 4P 1SDA066532R1 uses bimetallic element for overload detection and magnetic coil for short-circuit detection. This Molded Case Circuit Breaker trips with inverse time delay when continuous overload exceeds thermal setting, and trips instantly when short-circuit current reaches 800A. The four-pole structure breaks three phase and neutral conductor together to isolate fault circuit and protect downstream cables and loads.

Applications

ABB SACE FORMULA A1A 125 TMF 80-800 4P 1SDA066532R1 is deployed in three-phase four-wire distribution boards, industrial workshop branch feeders, water pump station power circuits, HVAC main power and general machine power supply protection. It serves as overcurrent and short-circuit protection for low voltage distribution replacement. ABB SACE FORMULA A1A 125 TMF 80-800 4P 1SDA066532R1 is stocked as spare molded case circuit breaker for SACE FORMULA power distribution assemblies.
