Designed & Assembled in the USA
- Combine 5 mA ground fault relay with a shunt trip circuit breaker for GFCI solution
- Meets intent of NEC 210.8 for commercial kitchens & applications requiring 4-6 mA ground fault detection.
- This solution guide is for most common single-phase 120 VAC & 3-phase 240 VAC applications. NK Technologies offers a full line of ground fault relays.
- Contact NK Technologies for other use cases. sales@nktechnologies.com
Choose a GF Relay in 4 Easy Steps
1. GFCI Protection Level | 2. Listed UL 508 Preferred? | 3. Choose Aperture Diameter Based on Wire Bundle Diameter | 4. Pair with Shunt Trip Circuit Breaker | ||||||||
Personnel GFCI | Process & Equipment GFPE | Listed UL 508 | Recognized UL 1053 | Aperture | Single Phase | 3-Phase | Use 120 or 240 or 480 VAC circuit breaker with 120 VAC rated shunt trip solenoid | ||||
< 50A | 60A | > 60A | |||||||||
5 mA |  | 1.76" | 4-wire Wye | YES | AGL & AGU are UL Listed to UL 508 for applications where code requires a "listed device." Factory calibrated for 5 mA (Class A) trip point. | ||||||
0.75" | YES | YES | 3-wire Delta | ||||||||
10 mA & 30 mA |  | 0.75" | YES | YES | AG3 provides field adjustable settings for personnel (5 mA) and process/equipment protection (10 mA & 30 mA) | ||||||
NEC requires 4-6 mA for personnel protection | All models UL tested | Monitored wire bundle must pass through relay aperture. AGL offers larger diameter than AGU/AG3 for 3-phase >60A | |||||||||
