SIEMENS 3VL9400-3HF05

SIEMENS 3VL9400-3HF05 is rugged shunt trip release modular accessory for Siemens SENTRON 3VL series moulded case circuit breaker (MCCB), designed for 3VL4 frame breaker. The shunt trip coil assembly enables remote electrical tripping of MCCB via control signal, used in emergency power cut-off circuits. This shunt trip release is installed inside MCCB housing, vibration-resistant construction to withstand salt mist, heavy vibration and electromagnetic interference in marine machinery spaces.

This component delivers remote breaker tripping & emergency cut-off interlock logic control. The remote breaker tripping & emergency cut-off interlock logic control receives energization command from PLC, emergency push button or vessel alarm system. The remote breaker tripping & emergency cut-off interlock logic control pulls the internal trip mechanism to open the main contacts of MCCB instantly once energized. The remote breaker tripping & emergency cut-off interlock logic control executes remote shutdown for main feeders and large motor circuits under fault conditions. The remote breaker tripping & emergency cut-off interlock logic control provides safety interlock function for shipboard emergency protection.

This SIEMENS spare is an essential MCCB modular accessory spare for low voltage switchboard overhaul. The MCCB modular accessory spare can replace faulty 3VL9400-3HF05 shunt trip assemblies directly. The MCCB modular accessory spare meets IEC electrical safety specifications. The MCCB modular accessory spare is widely fitted on cargo ships, tankers and offshore platform Siemens 3VL power distribution panels.

SIEMENS 3VL9400-3HF05 shunt trip release is modular accessory for 3VL series MCCB. It realizes remote electrical tripping of circuit breaker for emergency protection, performing reliably under vibration and humid industrial & marine machinery room environments.
