Yaskawa's Bestact high capacity 3 and 5 amp reed relays (RI & RZDR- series) offer industry DIP standard mounting format. They have UL/cUL recognition for gaseous Class I, Division 2 hazardous locations or corrosive environments and have been shown to significantly reduce downtime and/or maintenance costs. These relays have pilot duty inductive switch ratings of 360VA (AC), 69VA (DC) and horsepower ratings of 0.5 and 1/8 HP respectively. For low-level loads, they exhibit a wiping action that keeps contact resistance very low and stable. 2 and 4-pole configurations of normally open and normally closed contacts are available.

The E 492 wattmetric relay receives information on the voltage (V) and on the current, calculates the cos q value, therefore the following:
(ACTIVE POWER) w = 1.73 cos q
An active power relay is typically used to check the active power absorbed by an electric motor which provides direct information on the load applied to that motor. Such information is more accurate than the one given by the current value. Actually, the cos q variations can change the power values without affecting current values markedly.
