Bolatus Battery Isolator Switch 200A for Vehicles

This heavy-duty battery isolator switch offers a simple and reliable way to cut power for cars, trucks, boats, caravans and other 12 V to 48 V systems, helping prevent battery drain and providing an easy safety shutdown. It is particularly useful for seasonal vehicles or boats that need a main off point to prevent parasitic draws, and it supports higher surge currents for demanding starter circuits.

Key Points

The switch features clear colour-coded positions for fast identification, with green for ON and red for OFF. According to the manufacturer the unit is rated for 200 A continuous at 12 V, with intermittent and instantaneous surge capacities listed for short events. Simple two-screw connections fit M10 ring terminals and the body is moulded from ABS plastic for basic impact resistance. Consider measuring your installation space carefully before purchase, because correct fitment depends on matching the terminal spacing and ring size.

Usage Recommendations

Install the switch in an accessible location near the battery or on a dashboard panel so it can be operated quickly when required. Tighten terminal screws to the torque recommended for M10 connections and use properly sized ring terminals to avoid poor contact or overheating. The device only disconnects power mechanically and does not include fusing or overcurrent protection, so ensure appropriate fuses or circuit breakers remain in the system as required.

Positive Aspects

The tin-plated copper construction improves resistance to oxidation while preserving conductivity, which may extend service life in marine or damp environments. Colour-coded ON and OFF markings reduce user error when engaging the master cut-off. The broad 12 V to 48 V compatibility makes the switch suitable for a variety of applications from leisure vehicles to light commercial equipment, though it may not replace more complex battery management systems where automated isolation or monitoring is needed.
