SCHNEIDER 33659 VOLTAGE RELEASE MX/XF 24/30 VDC/AC

SCHNEIDER 33659 is the MX shunt trip release (also compatible as XF closing coil) for Schneider ComPacT NS / MasterPact NT air circuit breakers, control voltage range 24V AC 50/60Hz and 24–30V DC. The voltage release acts as an auxiliary electromagnetic coil for remote breaker control. The MX shunt trip coil instantly opens the circuit breaker when control voltage is applied, used for emergency shutdown and remote tripping. The XF closing coil performs remote closing command when energized, realizing full electrical remote operation of the air breaker. The voltage release features fast response time, about 50ms for MX tripping, and supports impulse signal trigger for safety interlock loops. The voltage release can be field-installed on fixed or drawout type ComPacT NS and MasterPact NT breakers without major breaker disassembly.

SCHNEIDER 33659 coil assembly adopts compact enclosed construction designed for internal mounting inside air circuit breakers. The electromagnetic coil has built-in surge suppression to resist transient voltage spikes and electrical noise from industrial and marine power networks. The electromagnetic coil holds IEC 60947-2 compliance and has stable operating threshold: MX trips reliably above 0.7 × Un; XF closes reliably above 0.85 × Un. The electromagnetic coil consumes low holding power and is tested for high mechanical endurance to match frequent breaker operation cycles. The electromagnetic coil is a genuine Schneider spare accessory for power distribution breaker retrofit and maintenance.

SCHNEIDER 33659 is widely used on marine main switchboards, industrial power plants, commercial building low voltage distribution systems for emergency stop and remote breaker control. The industrial spare part can replace defective MX/XF coils to restore remote tripping and closing function of air circuit breakers rapidly. The industrial spare part matches original mechanical and electrical specifications for direct breaker installation replacement. The industrial spare part has clear part marking for fast identification and stock management. The industrial spare part reduces power system downtime during breaker overhaul and power control system upgrade.
