SKU CH-ZTYH-342NA

Protects a single 240 V AC circuit at 5 A with Schneider Electric reliability

  • Product typeCircuit Breaker Accessories
  • Rated for 240 VAC single-phase circuits
  • 5 A trip current protects downstream wiring
  • Single-pole design fits standard DIN rail
  • Schneider Electric manufacture ensures consistent quality
  • First listed by manufacturer in 2020

Purpose and Rating

This Schneider Electric miniature circuit breaker provides 5 A single-pole protection at 240 V AC for residential or light-commercial switchboards. It is intended for installers who need a compact device to safeguard one live conductor against overload and short-circuit faults.

Sustained Operation

The breaker carries its rated current continuously without nuisance tripping and interrupts fault currents within the limits defined by its tripping curve. Thermal and magnetic elements work together so that prolonged overloads and sudden short circuits are both cleared reliably.

Deciding Specification

The 5 A rating determines whether this device matches the circuit design; a higher or lower value would not coordinate with the cable and load calculations. Buyers who need a different current rating or multi-pole configuration must select another part.

Questions about this item

Does the 5 A miniature circuit breaker run silently and without noticeable heat during continuous operation?

The device operates without a fan and produces no audible noise; heat rise stays within the limits defined for a 5 A breaker under normal load.

What existing electrical infrastructure is required to install this 1-pole Schneider Electric breaker?

It fits a standard DIN-rail distribution board and needs a 240 VAC single-phase supply with an upstream protective device already in place.

Will this 2020-listed 5 A breaker coordinate properly with older circuit breakers already in my panel?

Its tripping characteristic follows the same IEC curves used for decades, so selectivity with legacy breakers of matching rating is maintained.
