Blue Sea BS 7700 and MS 7702 ML-RBS remote-controlled battery master switch provides safe and convenient on/off switching between the battery and consumers. The 500 amp magnetic latching switch allows for high current draw under load, either manually or from a remote location.
The BlueSea BS 7700 and MS 7702 ML-RBS are mounted near the battery, which minimizes cable lengths for large cross-sections and saves costs. Switching is done via the remote control switch or directly on the master switch. The switch only consumes power during the actual switching process (<100mA). In the ON or OFF position, it consumes no power. The remote control switch can be installed in the cockpit area. The switch is IP66 moisture-protected and thus highly corrosion-resistant.
KEY FEATURES
- Manual override knob provides added safety, allowing control with or without power and providing LOCKED OFF capability for servicing
- LED output for remote indication of switch status - requires optional LED
- 3/8"-16 tinned copper studs for maximum conductivity and corrosion resistance
- 7/8" (22 mm) stud length accepts multiple cable lugs
- Label recesses for circuit identification
- Silver alloy contacts provide high reliability for switching live loads
TECHNICAL DETAILS
- Circuit connection: tinned wire
- Nominal voltage: 12V or 24V DC
- Manual control: yes (The manual switch offers additional safety, allowing control with or without power and providing LOCK OFF capability for servicing.)
- Coil function: Bi-Stable (The automatic unlock feature provides 500A switching and functions of current ML Remote Battery Switches, but can be controlled with SPST or SPDT switches for applications where a normally open relay is desired.)
- Mounting: #10
- Operating current: 0mA at 25°C Nominal VDC
- Operating current during state change: <7A (40 ms)
- Terminal stud torque: 15.82 Nm
- Voltage range: 10.1 to 16.5V DC
- Continuous current rating: 500 Amp.
- Peak current rating: 700A (5 min)
- Cranking current 30 Sec.: 1450A DC (the current required by the starter before starting the engine. The cranking current varies significantly during the starting cycle. Initially, there is a large surge of current required to overcome the engine's inertia and compression. This surge can be two to four times the average cranking current. The cranking current is used for sizing batteries, cables, and battery switches.)
