Instead of wiring six separate single circuit breakers back to a common bus, this block combines the common bus and six switched breaker positions into one compact, panel-mount unit, simplifying installation and reducing wiring clutter on the boat's electrical panel.\u003c\/p\u003e\u003cp\u003eEach of the six positions is rated up to 32 amps DC at 32 volts maximum, while the block as a whole is rated up to 100 amps common source. The busses and screw terminals are tin-plated copper and accept ring terminals for a secure connection. Quick connect clips allow the circuit breakers to snap easily into place in the block, and breakouts allow wire access from two directions to accommodate different wiring layouts. A clear insulating cover with square format label recesses lets each circuit be labeled while satisfying ABYC and USCG insulation requirements. Two ST-CLB terminal block jumpers can be added to allow three of the switched circuits to run on a non-24-hour source, giving flexibility for circuits like bilge pumps, clocks, or alarms that need to stay powered independently of the main switched circuits.\u003c\/p\u003e\u003cp\u003eThis circuit breaker block is intended for DC electrical panels on boats where multiple lower-amperage circuits, such as switched accessories, lighting, or electronics, are fed from a single power source.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea

The Blue Sea Systems ST-CLB block, part number 5052, distributes power from a single common source to six individually switched circuits, so it is used to feed multiple lower-amperage DC circuits, such as accessories, lighting, or electronics, from one power feed on a marine electrical panel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many amps does each circuit position handle?\u003c\/strong\u003e Each of the six switched positions on the 5052 block is rated up to 32 amps DC, while the block's common source bus is rated up to 100 amps total.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage is the ST-CLB 5052 block rated for?\u003c\/strong\u003e It is rated for a maximum of 32 volts DC, matching standard 12V and 24V marine electrical systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the block accept ring terminals?\u003c\/strong\u003e Yes, the busses and screw terminals on the Blue Sea Systems 5052 are tin-plated copper and accept ring terminals for a secure connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 5052 circuit breaker block ABYC compliant?\u003c\/strong\u003e Yes, the clear insulating cover on the 5052 satisfies ABYC and USCG insulation requirements while still allowing each circuit to be labeled.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does wiring access work on this block?\u003c\/strong\u003e Breakouts on the ST-CLB block allow wire access from two directions, giving flexibility for how cables are routed to and from the block.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan some circuits on the block run independently of the others?\u003c\/strong\u003e Yes, adding two ST-CLB terminal block jumpers allows three of the six switched circuits to be powered from a non-24-hour source separate from the other circuits, which is useful for loads like bilge pumps, a clock, or alarm circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the ST-CLB block mount to the breakers?\u003c\/strong\u003e The 5052 block uses quick connect clips that allow standard circuit breakers to snap easily into place in each of the six positions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 5052 different from wiring six separate circuit breakers?\u003c\/strong\u003e The ST-CLB block combines the common source bus and six switched breaker positions into one unit, so installers do not need to individually wire six separate single circuit breakers back to a common bus.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the weight of the Blue Sea Systems 5052 circuit breaker block?\u003c\/strong\u003e The 5052 circuit breaker block weighs 0.75 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the internal busses made of?\u003c\/strong\u003e The internal busses and screw terminals on the 5052 are tin-plated copper.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default
