Hager SBR364 Modular Switch Disconnector Isolator 63A 3 Pole 400V 3 Module Red Toggle DIN Rail

Description

Three-phase 63A isolation with 50mm terminals.

The Hager SBR364 is a 63A three-pole modular switch disconnector (isolator) with a red toggle and high-capacity 50mm terminals, giving safe, visible manual isolation of a three-phase 400V circuit from a 3-module DIN rail body.

Why it Matters

Isolate all three phases at once.
The SBR364 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 AC22 duty at 63A to IEC 60947-3, it makes and breaks mixed resistive and inductive loads, backed by a 1.33kA making capacity and 0.94kA short-time withstand – suited to sub-main and sub-circuit isolation rather than automatic tripping.

50mm terminals in three modules.
The SBR364 spans three DIN modules (52.5mm wide, 83mm high, 68mm deep) on standard 35mm rail. Its high-capacity terminals take rigid conductors from 6 up to 50mm² and flexible from 6 up to 35mm² per pole at a 3.6Nm tightening torque – more headroom than a typical 63A device – while dissipating just 6.6W and lasting 40,000 mechanical operations.

Built for Australian switchboards.
With a 6kV rated impulse withstand voltage and IP20 protection, the SBR364 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 SBR364 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 SBR364 rated for?
400V AC three-phase at 63A under the AC21/AC22 utilisation categories, covering resistive and mixed inductive loads.

Q: What cable can the SBR364 terminals take?
Rigid conductors from 6 to 50mm² and flexible from 6 to 35mm² per pole, tightened to 3.6Nm – high-capacity terminals for a 63A three-phase feed.
