The TB-Series is a space-saving, tandem pole circuit breaker specifically designed to fit a two pole breaker into one rack unit making it ideal for datacom and PDU applications.
The TB-Series is designed with a common trip linkage ensuring if one pole trips, the tandem pole simultaneously trips. It also features a trip-free mechanism, a safety feature making it impossible to manually hold the contacts closed during overcurrent or fault conditions. The TB-Series is available with an optional handle guard to prevent inadvertent actuation and an optional auxiliary switch.
2 poles; ratings from 0.10 to 20 amps, 120/240VAC; UL 489 Listed, TUV, IEC/EN 60947-2.
