Why it Matters

Isolate all three phases at once.
The SBR380 is a three-pole switch disconnector, not a circuit breaker – its role is to positively disconnect all three phases of a 400V circuit together for maintenance and safe working, with the red toggle giving clear on/off indication at the board. Rated for AC22A duty at 80A to IEC 60947-3, it makes and breaks mixed resistive and inductive loads, backed by a 1.35kA making capacity and 0.96kA short-time withstand – sitting between the 63A and 100A models for mid-range three-phase feeds.

Heavy three-phase cable, three modules.
The SBR380 spans three DIN modules (52.5mm wide, 83mm high, 68mm deep) on standard 35mm rail. Its high-capacity terminals accept rigid conductors from 6 up to 50mm² and flexible from 6 up to 35mm² per pole at a 3.6Nm tightening torque – the cabling an 80A three-phase feed runs – while dissipating 8.1W and lasting 40,000 mechanical operations.

Built for Australian switchboards.
With a 6kV rated impulse withstand voltage and IP20 protection, the SBR380 operates from -20°C to 70°C, covering meter boxes, plant rooms and commercial and industrial distribution boards 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 SBR380 a circuit breaker?
No. It is a three-pole switch disconnector (isolator) for safe manual isolation of a three-phase circuit; it does not provide automatic overload or short-circuit tripping like an MCB or MCCB.

Q: What voltage and load is the SBR380 rated for?
400V AC three-phase at 80A under the AC21A/AC22A utilisation categories, covering resistive and mixed inductive loads.

Q: What cable can the SBR380 terminals take?
Rigid conductors from 6 to 50mm² and flexible from 6 to 35mm² per pole, tightened to 3.6Nm – sized for an 80A three-phase feed.
