Example – a breaker with catalog number
SKPC3612L4R6 has the following features:
1 SK1200 frame (SK)
2 100 kA at 480 Vac Standard UL rating (PC)
3 3 pole, 600 Vac maximum (36)
4 1200 A sensors (12)
5 Long-time, Short-time, Instantaneous and Ground
Fault functions (L4)
6 RELT – Reduced Energy Let-Through (R)
7 Advance Metering, Modbus Communications, and
Waveform Capture (6)
2. Following the instructions supplied with the rating
plug, install the plug into the breaker body. Available
rating plugs, with their catalog numbers, are listed in
Table 2.
1. SKT and SKS catalog codes are optimized for selectivity and will carry a
480Vac maximum voltage rating.
