Protective Relays 20-000 Series Product Facts n Product Specifications #6 - 32 STUDS 6 PLACES Function 81 O R 4 1/2 Operation The normally open contacts close, and the normally closed contacts open, at all frequencies above the set point. The contacts in the connection diagram, are shown in the de-energized position (below the trip set point). 3 13/16 3.0 1 /2 3 7 /8 3 The output contacts of frequency relays are energized when the frequency exceeds the adjustable set point. Overfrequency and underfrequency relays are available in 50, 60 and 400Hz. Combination over/underfrequency “band pass” relays are also available. These are energized at rated frequency and de-energized during overfrequency or underfrequency conditions. Frequency Differential relays are energized between the preset frequencies. The pick-up and drop-out frequency settings are independently adjustable. 2 3/4 1/2 3 Input Voltage (±10%) — 120 VAC, Single Phase Frequencies Range (adjustable) — See Ordering Information Differential — Frequency pick-up to drop-out differential is 1% max Temperature Range — -40°C to +85°C Temperature Drift — ± 1% frequency error over temperature range Voltage Error — ± 1% for input voltage of 120 VAC ± 10% Contact Ratings — 5 amp resistive at 120 VAC or 28 VDC Output Contacts — One set N.O., one set N.C. Notes: 1. Remove screw for access to trip adjustment. 11/64" DIA. 4 MTG. HOLES Note: Dimensions in inches.
