residual current operated circuit breaker
Scope of application |
TRL-32 series are mainly applied to the AC50/60HZ single circuit with rated voltage 115V/230V, rated current up to 32A providing protect human body against electric shock due to electric leakage. Meanwhile it can be used prevent the dangerous fire by fault grounding current due to damaged in insulation.
This product has character of small volume, high breaking capacitance operation reliably and environment. It is best ideal product to protect electric shock and creepage on electric water heater, solar water heater, watering trough, fridge and washer etc. |
