30 A Plug Fuse for 125 V AC Circuits
This Bussmann S-series plug fuse provides 30 A time-delay protection for 125 V AC circuits. The ceramic-bodied, dual-element design includes a rejection feature that prevents incorrect installation. It is suited for residential and light-commercial panels that require indicating fuses. The pack contains four fuses for multi-circuit or spare inventory needs.
Sustained Overload Behaviour and Interrupt Capacity
The dual-element construction tolerates temporary inrush currents without nuisance opening while clearing sustained overloads. An interrupt rating of 10 kA at 125 V AC ensures the fuse can safely break high fault currents. The time-delay characteristic reduces downtime on circuits with motor loads or transformer inrush. The indicating window gives visual confirmation when the element has opened.
Compatibility Limits of the Edison-Base Standard
The rejection base fits only matching Edison-base fuseholders that accept the S-series profile, preventing use of lower-rated fuses. It complies with UL 248-11, CSA Class 1423-01 and CE requirements for plug-type fuses. Circuits exceeding 125 V AC or requiring a higher interrupt rating fall outside this fuse's certified application. The four-pack quantity suits panels with multiple protected branches.

Questions about this item
How much heat does the S-30 plug fuse generate when running at 30 A all day?
The ceramic-bodied, dual-element S-30 plug fuse operates at 125 V AC with a 10 kA interrupt rating; normal load produces only minimal warmth inside a standard fuse block.
What fuse block or panel must I already own to install these S-30 fuses?
A standard Edison-base plug-fuse holder rated for 125 V AC and 30 A that accepts S-series rejection-base fuses is required for installation.
Will these S-30 fuses coordinate with older 125 V AC Type-S or SLO fuses still in my panel?
Yes — the S-30 is equivalent to Bussmann S, Littelfuse S, SLO and SOO series, so it coordinates with existing 125 V AC Type-S rejection-base fuses.
