ABB brand S91 series plug-in circuit breaker, 3kA, available in 6, 10, 16, 20, 25, 32 and 40 amp ratings. 3kA short circuit rating. Approval ESV160229.
Designed to replace porcelain fuses on older switchboards which do not have DIN rail mountings. Although these circuit breakers can be fitted directly to a lot of the older porcelain bases, to comply with current standards the matching plastic safety base should be replaced as well.
Tip: It is often better value to consider a surface enclosure (or even a complete new distribution board) and modern circuit breakers (much higher protection rating) when replacing old porcelain fuses. Please select amp rating and quantity using the dropdown box
