Why it Matters

Isolation you can see.
The SBR140 is a switch disconnector, not a circuit breaker – its role 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 AC22A duty at 40A, it makes and breaks mixed resistive and inductive loads, and is built specifically for the manual load-break a sub-main or circuit isolator needs rather than automatic tripping.

Small footprint, long life.
The SBR140 takes just one DIN module (17.5mm wide, 83mm high, 68mm deep) on standard 35mm rail, so it fits a single pole space in the switchboard. Terminals accept rigid conductors from 2.5 up to 25mm² (flexible to 16mm²) at a 2.8Nm tightening torque, it dissipates only 1.1W at full load, and it is rated for 60,000 mechanical operations – a durable, set-and-forget isolator.

Built for Australian boards.
With a 6kV rated impulse withstand voltage and IP20 protection, the SBR140 operates from -20°C to 70°C, covering meter boxes, plant rooms and enclosures across Australian conditions on standard 35mm DIN rail. Optional Hager accessories include the MZN175 padlockable locking kit for safe lock-off, MZN121 inter-pole barriers, MZN120 terminal shield and the ESC080 auxiliary contact.

Q: Is the Hager SBR140 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 does AC22A mean on the SBR140?
AC22A is a utilisation category for switching mixed resistive and inductive loads, meaning the SBR140 is rated to make and break such loads at its full 40A rating.

Q: Can the SBR140 be locked off for isolation?
Yes. The optional MZN175 padlockable locking kit lets you lock the toggle in the off position for safe isolation during maintenance.
