What is the purpose of a fault signal contact?
A fault signal contact is used to provide a remote indication of a trip condition in a circuit breaker. When the associated circuit breaker trips due to a fault, the fault signal contact changes state, allowing for an external signal or alarm to be activated, indicating the need for attention.
Can the fault signal contact be mounted on any miniature circuit breaker?
The fault signal contact is designed to be mounted on specific types of miniature circuit breakers, such as the 5SL, 5SY, 5SP series, RCBO 5SU1, and RCD 5SV. It is important to check compatibility with the specific breaker model before installation.
What type of contacts does the fault signal contact have?
The fault signal contact comes with one normally closed (NC) contact and one normally open (NO) contact, providing flexibility for different signalling requirements.
How many pitch units in width does the fault signal contact occupy?
The fault signal contact occupies 0.5 pitch units in width, making it a compact addition to a circuit breaker without requiring much additional space.
Is there a specific voltage type for the control voltage of the fault signal contact?
The fault signal contact is designed to work with both AC and DC control voltages, providing versatility for use in various electrical systems.
What is the insulation voltage rating for this fault signal contact?
The insulation voltage rating for the fault signal contact is typically rated at 440 V.
What is the surge voltage resistance of the fault signal contact?
The surge voltage resistance of the fault signal contact is rated at 4 kV.
What is the typical electrical endurance of the fault signal contact?
The typical electrical endurance of the fault signal contact is around 12,000 to 20,000 switching cycles, depending on the specific model.
What is the protection class IP rating of the fault signal contact?
The fault signal contact has a protection class IP rating of IP20.
Can the fault signal contact be used with a handle coupler?
Yes, the fault signal contact can be used with a handle coupler, such as the 5ST3805-1, which may be required for certain applications.
