RL-RCM300-POS 12V-24V 300A Positiv Remote Battery Disconnect Switch
Part#RL-RCM300-POS
This heavy-duty 12V-24V remote battery disconnect switch mounts directly on the positive terminal and delivers a robust 300A continuous and 1000A cranking current rating.
Featuring an automatic 11.8V low-voltage cutoff and a high-voltage remote lockout for safe driving, this smart isolator prevents parasitic drain during long-term vehicle, boat, or RV storage.
RL-RCM300-POS 12V-24V 300A Positiv Remote Battery Disconnect Switch Features
- Positive-Terminal Power Isolation
This remote battery disconnect switch mounts directly onto the positive battery terminal to manage the vehicle’s primary power distribution. An included negative sensing wire connects to the opposite terminal to enable precise real-time voltage monitoring and advanced circuit control.
- Automatic Low-Voltage Cutoff
The intelligent low-voltage protection program automatically cuts vehicle power after 120 seconds if the battery drops below 11.8V (or 23V for 24V systems). This automated disconnect system guards against battery over-discharge to guarantee reliable engine starting after long-term storage.
- Driving Protection Mechanism
An automatic high-voltage lockout disables the wireless remote control once the alternator raises system voltage above 13.2V (or 25V) during engine operation. This vital safety feature eliminates the risk of accidental power shutoff while driving on highways or open waters.
- High-Current Electrical Rating
The heavy-duty brass contact block easily supports a continuous current load of 300A and up to 1000A of engine cranking surge for 30 seconds. This rugged electrical architecture handles high-demand starters in commercial trucks, RVs, marine yachts, and agricultural equipment.
- Micro-Ampere Standby Efficiency
An ultra-low standby current of only 3mA prevents the switch from draining the vehicle battery during extended winter storage. The digital LED screen paired with status indicator lights provides immediate visual feedback of current voltage levels and system modes.
