Blue Sea Systems Switch Battery e-Series ON/OFF

Blue Sea Systems e-Series 9003e Single Circuit ON/OFF marine battery switch for use with inboard petrol and diesel engines. This switch has a 350A continuous current rating, a maximum cranking/starting rating of 1200A for 30 secs and a voltage rating of 48V DC, making it suitable for use with 12V, 24V & 36V systems. The single circuit ON/OFF configuration allows switching a single battery (or bank of batteries) to a single load group, and it can be used to disconnect the battery in emergencies or when the vessel is not in use.

The e-Series range of battery switches are engineered for use in harsh marine environments in applications requiring high power output, high reliability, and low heat generation. The M10 (3/8") tin-plated copper terminal studs provide maximum conductivity and corrosion resistance, and their 22mm length allows multiple cable terminals to be connected. The studs are a one-piece design, meaning they cannot work loose over time and the risk of over heating is reduced.

The ignition-protected case design is standardised across the range and has an IP66 waterproof rating, can accept cables up to 120mm² (4/0 AWG) in cross-section, and can be surface or rear panel mounted. The design of the actuating knob includes raised features that allow the position of the switch to be determined by feel - useful if operating in confined spaces.

An optional label set is available (see Further Information below).

This switch is also available with an Alternator Field Disconnect (AFD) facility (see Further Information below).
