NBSe TQC Series 2P 50A Plug-in type circuit breaker, fuses and circuit breakers
Description:
This TQC circuit breaker safely cuts off power immediately if the circuit becomes overloaded (too many electrical appliances being used), or short circuited (a faulty appliance). Plug in circuit breakers are more reliable and have a faster response time then standard rewireable fuses. Once installed, they do not require any tools to be reset, simply switch back on once the fault has been fixed.
Features:
One-piece moulded case construction.
Hardened cradle for positive action under fault conditions.
Heavy duty line terminal and spring clip for quick loadcentre installation and cool coperation.
Silver tungsten alloy contacts.
Magnetic assembly for reliable short circuit protection.
Large gas port for venting short circuit gases safely into loadcentre gutter.
Calibrated one-piece bimetal for reliable thermal trip function.

What is the difference between Plug-in and Fixed Circuit Breaker ?
The plug-in version makes it possible to:
- Extract and/or rapidly replace the circuit breaker without having to touch the connections on the base
- Allow for the addition of future circuits by installing bases that will be equipped with a circuit breaker at a later date
- Isolate the power circuits when the device is mounted on or through a panel. It acts as a barrier for the connections of the plug-in base. Insulation is made complete by the mandatory short terminal shields on the device.The degrees of protection are: circuit breaker plugged in = IP4
circuit breaker removed = IP2
circuit breaker removed,base equipped with shutters = IP4.
