TOC-2 transformer clamp – compact, M12 / M20 / M30
Clamps certified by SEP-BBJ
TOC-2 clamps hold a certificate of conformity issued by SEP – Quality Testing Office (BBJ), a certification body accredited by PCA (No. AC 012). TOC-1 M12 clamps from the same family, together with the OZNN cover, hold Certificate of Conformity No. Z/12/004/26.
Two clamps, the same connectivity
TOC-1
- Body with an offset foot – two locking screws on the foot, below the head
- Sockets sit higher above the cover – easy access with thick conductors
- Our standard for MarkoEco2
TOC-2
- Compact body – sockets in the head, slotted shank, locking screws on the side
- Smaller footprint on the cover – for closely spaced LV bushings or under a cover
- Same M12/M20/M30 thread and the same conductor sizes
Both clamps are tin-plated brass forgings with stainless steel fastening screws and fit the OZNN cover. Not sure which one? Tell us the transformer type and we will advise.
