Functional Devices RIB01P30-NC Enclosed Power Relay 30A DPST-NC 120VAC

The Functional Devices RIB01P30-NC is a Relay In a Box (RIB) Power Series enclosed relay featuring a 30-amp DPST normally-closed (NC) contact configuration with a 120 VAC coil. Designed for higher-amperage commercial and industrial applications, this relay is ideal for building automation systems (BAS), HVAC control, low-horsepower motor switching, and lighting load management.

Key Features:

• Contact Configuration: DPST-NC (Double Pole Single Throw, Normally Closed) — both poles remain closed by default until the coil is energized, making it ideal for fail-safe circuit designs
• Contact Rating: 30A resistive @ 300 VAC; 3 HP motor; 20A ballast; 1640 VA pilot duty
• Coil Voltage: 120 VAC, 50/60 Hz
• Relay Status Indicator: LED — illuminates when relay is activated
• Expected Relay Life: 10 million cycles minimum mechanical
• Gold Flash contacts for enhanced conductivity and reliability
• Housing: NEMA 1, UL Accepted for use in plenum-rated environments
• Conduit Hub: 1/2" NPT and 3/4" NPT protruding nipple for conduit entry
• Wire Leads: 16", 600V rated
• Operating Temperature: -30° to 140°F (-34° to 60°C)
• Operating Humidity: 5% to 95% non-condensing
• Operate Time: 18ms
• Override Switch: None (no manual override on this model)
• Origin: Made of US and non-US parts

Approvals & Certifications: UL Listed, UL 916 Energy Management, UL 864 Fire, C-UL Listed, California State Fire Marshal (CSFM), CE, RoHS

Dimensions: 4.000" H x 4.000" W x 1.810" D (with 0.50" NPT nipple)

The RIB Power Series comes fully pre-mounted and pre-wired in its enclosure, eliminating the need to purchase separate relay components, sockets, mounting rails, and enclosures. Installation is straightforward: route wires and the NPT nipple through a conduit knockout, secure with the locknut, and connect the leads. This relay is not rated for electronic loads such as LED drivers or electronic ballasts — use only with rated resistive or inductive loads.
