Rezap Modular

Compact LV multi-shot auto-recloser

Protects the LV network during intermittent LV cable faults and safely restores customer supplies fast while assisting fault location


Intermittent faults can be a major challenge for customers, often taking Operators an hour or more to restore supply.

Rezap Modular is a compact multi-shot circuit breaker and auto-recloser that brings full Rezap functionality to fuse panels with severe space restrictions. Fitting virtually all existing fuse cabinets, Rezap Modular rapidly reconnects customers after intermittent LV cable faults, minimising interruptions while keeping staff safe.

Rezap Modular interrupts supply in the event of an overcurrent event, automatically re-energising the circuit after a short delay. Intelligent electronics and programmable delay characteristics allow intermittent faults to be cleared and restore supplies, or conditioned to accelerate collection of fault data to allow subsequent repair.

Rezap Modular also collects power quality and fault information to enable single-ended fault location.

Rapid reconnection during faults

Minimizes impact of intermittent faults on supply continuity to reduce customer inconvenience and CI/CMLs.

Location icon

Assists fault location

Provides power quality and load profiling information that can be used to support single-ended fault location.


Enhanced staff safety

Allows the Operator to safely re-energize the circuit via a low-power radio link up to a distance of 30 meters.

Efficient operations

Auto or manual reclosing

Can be configured in two operational modes, to perform reclosing either automatically or under manual control.


  • Compact form factor, fitting virtually all existing fuse cabinets
  • High current rating up to 400A
  • Wireless remote operation for greater operator safety
  • Combined fault location and load profiling enables single ended fault location (SELF)
  • Web based management interface with message forwarding via SMS and email
  • ‘Fault thumping mode’ enables a 20% increase in energy to either pass permanent faults or to create enough noise at the location of the fault for it to be heard above ground
  • Light and easy to carry, ideal for single-person operation
