XT IEC Power Control

Manual Motor Protectors

Product Selection

Table 169. XTPT Transformer Protective Circuit Breakers — Global and North American Ratings



Type 1 and Type 2 Coordination

For the protection of transformers with a high inrush current. Fixed short-circuit trip of 15 – 22 times max. settings of FLA



Select Manual Transformer Protectors by full load amperes. Maximum Motor Ratings (kW, hp) are for reference only.



In this range, calculate motor rating according to rated current. Speciﬁed values to NEC Table 430-150.



XTPT can be used also for transformer protection, provided the Pub51226 note label is applied next to the ﬁtted device.



For manual motor protective circuit breaker switching capacity, see Page 147.

Notes:

For the protection of transformers with a high inrush current.

Single-phasing sensitivity to IEC/EN 60947-4-1, VDE 0660 Part 102.

Can be snap-ﬁt to IEC/EN 60715 top-hat (DIN) with 7.5 or 15 mm height.
