ABB 1SFA619100R1076 Auxiliary Contact Block | 1NO+1NC Specs

Meta Description:​ ABB 1SFA019100R1076 auxiliary contact block. Key specs: 1NO+1NC, screw terminals, 10A. For SACE Tmax XT circuit breakers.

Product: ABB 1SFA619100R1076 Auxiliary Contact Block

The ABB 1SFA019100R1076 is a universal, snap-on auxiliary contact block designed for Tmax XT series molded case circuit breakers (MCCBs). It provides remote electrical signaling of the circuit breaker's status (ON/OFF or TRIPPED).

Key Features

• Universal Mounting:​ Fits all Tmax XT circuit breaker frame sizes (T1XT...T7XT) on both left and right sides.

• Snap-on Design:​ Easy to install without tools.

• Status Indication:​ Provides one normally open (NO) and one normally closed (NC) contact.

• Compact Size:​ Space-saving design for panel building.

Technical Specifications

Function & Wiring

This contact block mechanically follows the position of the circuit breaker's main contacts:

• The NO contact​ closes when the circuit breaker is ON.

• The NC contact​ closes when the circuit breaker is OFF​ or TRIPPED.

It is typically wired to indicator lights, PLC inputs, or alarm systems to provide remote status monitoring.

Typical Applications

• Remote indication of circuit breaker status (ON/OFF/TRIP) in control panels.

• Interlocking or control circuits that require confirmation of breaker state.

• Building Management Systems (BMS) or SCADA system integration.

Important Note

This is an auxiliary signaling device only. It does not​ provide any protection or control function for the circuit breaker itself. For shunt trip, under-voltage release, or other control functions, different accessory modules are required. Ensure the contact rating (AC-15/DC-13) is suitable for your control circuit's voltage and current.
