High current protection

High-current protection for main cables, winches and inverters

Main cables, anchor winches, bow thrusters and inverters need protection that carries high currents and interrupts safely in a short circuit. philippi offers SHB bolt-down fuses, Class T and strip fuses with matching holders, as well as resettable circuit breakers, from 25 A to 600 A.

In short: the main fuse belongs as close as possible to the positive terminal, no more than 17.8 cm away (ABYC E-11). With lithium batteries, only the SHB bolt-down fuse or Class T are permitted at the terminal.

The cable configurator calculates which fuse suits your cross-section in one step. The page Fuses on board gives an overview of all fuse types.

The products at a glance

  • SHB bolt-down fuse (MRBF): 30 to 300 A, M8 stud, 58 V DC, 10 kA breaking capacity. On the ABH 1 holder directly at the battery terminal or in the BS 5196 triple holder (up to 300 A) close to the terminal.
  • Class T fuses: 20,000 A breaking capacity at 125 V DC, holders for 110 to 200 A and 225 to 400 A, fuses up to 600 A. The main fuse for large lithium banks.
  • STS strip fuse with SHD holder: ceramic body with inspection window, M10 connection. Proven and economical for main cables with lead-acid, AGM and gel.
  • 8345 series circuit breaker: hydraulic-magnetic, 40 to 160 A, 80 V DC, tripping independent of ambient temperature. Switches and protects in one device, ideal for anchor winches.
  • TCB high-current circuit breaker: 25 to 100 A, 48 V DC, IP 67, manually operated. Not for starter motors.

Frequently asked questions

How far may the main fuse be from the positive terminal? No more than 17.8 cm according to ABYC E-11, ideally directly at the terminal. The cable section in front of it is unprotected in a short circuit; the SHB bolt-down fuse on the ABH 1 holder therefore sits directly on the terminal.

Which protection do I need with lithium batteries? At the terminal only the SHB bolt-down fuse (10 kA) or Class T (20 kA). Lithium banks deliver very high short-circuit currents that other types cannot interrupt safely.

Circuit breaker or fuse? An 8345 series circuit breaker can be reset after tripping and replaces main switch and fuse in one device. Fuses are cheaper but must be replaced after tripping.
