Bussmann 185070F-13-1 – Frequently Asked Questions

1) Can I use the Bussmann 185070F-13-1 breaker on a 12V or 24V DC vehicle system?
Yes. The Bussmann 1850 Series 185070F-13-1 is rated 42 Vdc, which is a maximum working voltage, so 12V and 24V DC systems fall within it. It is a DC-only device: do not put it on an AC branch circuit. Fault interruption is rated 3 kAIC at 30 Vdc, so the available short circuit current at the breaker location needs to sit under that.
2) What size circuit can the Bussmann 185070F-13-1 protect?
It is a 70 amp device, so it protects a branch whose continuous load and conductor ampacity are sized for 70A. Size the cable to the breaker, not the other way round. If your load draws more than 70A continuously you need a higher-rated breaker in the 1850 Series rather than this one.
3) Is this a resettable breaker or a one-time fuse?
The 185070F-13-1 is a circuit breaker, not a fuse. It trips on overcurrent and is put back into service rather than replaced, which is the reason it gets specified on DC distribution panels and mobile equipment where a blown element would mean carrying spares.
4) Will the Bussmann 185070F-13-1 hold up in a marine or engine compartment environment?
The housing is black thermoset plastic, a material chosen for heat and impact resistance, and the description lists marine and mobile electrical systems among its applications. Thermoset will not soften the way a thermoplastic case can near a heat source. It is still an open surface-mount device, so in a wet or spray location it belongs inside a protective enclosure.
5) I need to order a replacement for a 70A Bussmann 1850 breaker. What part number do I ask for?
Order by manufacturer part number 185070F-13-1. That is the Eaton Bussmann 1850 Series, 70A, 42 Vdc configuration, and the suffix matters because the 1850 family spans a range of amperages and terminal configurations. Matching the amperage alone is not enough if you want the same mounting and terminal arrangement.
6) Does this Bussmann breaker meet RoHS restricted-substance requirements for an OEM build?
Yes, the 1850 Series 185070F-13-1 is RoHS compliant, which covers the restricted-substance declaration most OEM and export bills of material ask for. That is the compliance our record carries for it.
