Surge Suppressors are used to suppress the high voltage spike that is generated when a relay or contactor coil is de-energized. The electromagnetic field across the coil generates a voltage spike in the wires of the control system causing interference on electronic devices and even it can cause destruction of sensitive devices or equipments.
• Limits the voltage peak coming from coils inductive discharging current.
• High energy absorption; good damping
• Un-polarized system
• Used on AC and DC coil
