Why it Matters

Isolation you can see.
The SBR164 is a switch disconnector, not a circuit breaker – its job is to positively disconnect a circuit for maintenance and safe working, with the red toggle giving clear on/off indication at the board. Rated for AC22 duty at 63A, it makes and breaks mixed resistive and inductive loads, and is built for the manual load-break a sub-main or main-switch isolator needs rather than automatic tripping. A 1.33kA making capacity and 0.94kA short-time withstand back its switching performance.

Heavy cable in one module.
The SBR164 fits just one DIN module (17.5mm wide, 83mm high, 68mm deep) on standard 35mm rail, yet its high-capacity terminals take rigid conductors up to 50mm² and flexible up to 35mm² at a 3.6Nm tightening torque – the larger cable a 63A sub-main typically runs. It dissipates little heat and is rated for 40,000 mechanical operations for dependable long-term service.

Built for Australian boards.
With a 6kV rated impulse withstand voltage and IP20 protection, the SBR164 operates across the full range of Australian switchboard conditions on standard 35mm DIN rail. Optional Hager accessories include the MZN175 padlockable locking kit for safe lock-off during isolation, MZN121 inter-pole barriers, MZN120 terminal shield and the ESC080 auxiliary contact.

Q: Is the Hager SBR164 a circuit breaker?
No. It is a switch disconnector (isolator) for safe manual on/off isolation of a circuit; it does not provide automatic overload or short-circuit tripping like an MCB.

Q: What cable can the SBR164 terminals take?
Rigid conductors up to 50mm² and flexible up to 35mm², tightened to 3.6Nm – high-capacity terminals sized for a 63A sub-main.

Q: What does AC22 mean on the SBR164?
AC22 is a utilisation category for switching mixed resistive and inductive loads, meaning the SBR164 is rated to make and break such loads at its full 63A rating.
