Heavy-Duty 12V/24V Split-Charge Solenoid Contactor (200A), 40A Bosch SPDT Relays, DIN-Rail Contactors & Solid-State Relay Pack (OGA-CMP-127)
Switch heavy 200A battery banks, 40A 12V water pumps, and AC/DC heating or siren loads automatically from float switches, thermostats, or ESP32/LoRa microcontrollers.
UK Blackout & Field Application
Microcontrollers, LoRa flood sensors, and small float switches can only pass milliamps—connecting them directly to a 15A sump pump or 150A battery bank melts the switch contacts immediately. This heavy relay and contactor pack lets low-power triggers safely switch massive 12V/24V/230V loads.
Engineered for Both across Great Britain. In a prolonged utility outage, Heavy-Duty 12V/24V Split-Charge Solenoid Contactor (200A), 40A Bosch SPDT Relays, DIN-Rail Contactors & Solid-State Relay Pack provides dependable off-grid capability, with plain-English commissioning documentation. Delivery times are confirmed when ordering opens.
