BEP 720B Heavy-Duty 600A Battery Master Switch

BEP 720 Heavy-Duty On/Off Battery Master Switch (Bulk Packaging)

The BEP 720B is an extra-heavy-duty 600A continuous On/Off manual battery master isolator switch designed to safely isolate high-output battery banks, large inverter systems, and multi-engine power feeds. Built to withstand high-current electrical loads up to 48V DC, it delivers low-resistance switching across modern 12V, 24V, and 48V DC marine architectures.

Constructed using fiber-reinforced, temperature-resistant polymers, the 720B utilizes BEP’s patented Contour Lock housing design, allowing it to seamlessly interlock with other Contour-series battery switches and distribution modules. It features self-cleaning sliding copper contacts, heavy-duty M12 (1/2 in) tinned-copper terminal studs to accommodate dual heavy-gauge battery cables, and removable side plates for clean wire routing. 

Key Features

• High Ampacity Contact Design: Self-cleaning copper sliding contacts handle heavy continuous current without contact pitting or welding.

• Modular Contour Lock System: Interlocking side slots allow ganging alongside busbars, fuses, and companion switches for clean panel layouts.

• Dual-Cable M12 Terminal Studs: Heavy-duty M12 (1/2 in) tinned copper studs accommodate stacked 3/0 AWG (95mm²) or 4/0 AWG (120mm²) battery lugs.

• Versatile Mounting Options: Supports surface mounting or recessed rear-panel flush mounting with a 3.75 in (∅ 95 mm) panel cutout.

• Control Knob Lockout Feature: Rotary control knob can be locked via a padlock (control cutout) to ensure maintenance safety and security.
