G2A ■ Relays Other than Standard Models Arc barrier equipped Built-in diode Built-in operation indicator G2A-432A-N The arc barrier equipped model is a relay designed to prevent arc short-circuiting between phases and can be used in a circuit which has potential difference between phases. The switching power of such a circuit with potential difference must be limited to less than 1/2 the rated load when using this Relay. The built-in diode model is a relay which incorporates a diode for absorption of the reverse voltage that may be generated when the coil is de-energized. Because the...

The PYF@A-TU is a high-humidity relay with nickel-plated rustproof terminal screws that are the same as the PYF@A in size. 2. The PYF14T is slightly different from the PYF14A(-TU) in shape and size. 3. The PYF@A-E is a finger-protection model, for which round terminals are not available. Use fork-shaped terminals or equivalent ones instead. PY14-3 Back-connecting Socket...

G2A Socket Mounting Plates (t = 1.6 mm) Use any of these plates when mounting two or more Sockets side-by-side PYP-1 (for Single Socket Mounting) PYP-18 and PYP-36 can be cut to a desired length for mounting less than 18 or 36 Sockets, respectively. 13.1 27.4 x 17 = 465.8±0.6 Safety Precautions Refer to Safety Precautions for All Relays. A DC coil model with a built-in indicator or built-in diode has coil polarity. Be sure to wire the terminals correctly, otherwise the diode may be broken or the operating indicator may not be lit. Furthermore, as a result of the short-circuiting of the...
