Excellent mvaa relay wiring diagram - Contacts are made from silver/copper alloy. Damage and changeover contacts and heavy responsibility magnetic blow-out contacts are available in diverse combinations. 2 and 3. When these are equipped. Breaking capacity curves for those contacts are proven in parent 4. Formed and located to ensure very reliable. Low resistance operation.

Heavy responsibility magnetic blow-out contacts are recommended for breaking heavy or extraordinarily inductive dc loads. Ordinary responsibility make. The indicator consists of a mask which on operation drops to reveal a huge crimson strip located diagonally on a rectangular white background. See table three.

Description mvaa relays are voltage operated attracted armature devices of compact layout with a tremendous movement and a high degree of mechanical balance. Voltage is carried out to the relay coils via an inner diode bridge which permits relays to be energised from ac or dc energy supplied. All relays observe iec 255. Figures 2 and 3 show traditional diagrams of relay sorts mvaa 11 and mvaa 14 respectively.

Defensive relays are specific measuring devices, the contacts of which need to now not be anticipated to replace massive electrical hundreds. In some cases, the protective relay may ride a circuit breaker directly, or in line with the coil rating and the range of circuits to be energised, may accomplish that the use of a mvaj tripping relay. The mvaj relay interfaces the protection relay with the circuit breaker to provide the higher touch capacity, extra contacts for tripping a couple of circuit breakers, manipulate capabilities, signalling and interlocking. The mvaj variety accommodates exceptionally dependable hinged armature relays designed to at once function circuit breaker trip coils. Constructed to very high specifications, the mvaj variety provides a particularly bendy and dependable hyperlink between the protecting relays and the circuit breakers.

Utility the sort mvaa is a low burden auxiliary relay which may be used where a scheme needs several contacts for event recording, alarm initiation, contact common sense preparations, and so forth the relay may be provided fitted with regular obligation contacts and/or with heavy obligation blow-out contacts.

Fashions to be had there are 5 variations of the mvaa relay, every with a specific type of touch reset mechanism. ?? mvaa 11 single element relay with self reset contacts. Two element model is type mvaa 21 • mvaa 12 unmarried element relay with a combination of self and hand reset contacts. Element version is type mvaa 22 • mvaa13 unmarried element relay with hand reset contacts. Element model is type mvaa 23 • mvaa 14 unmarried element relay with electrical reset contacts • mvaa 15 single detail relay with hand and electrical reset contacts. The contacts can be reset either electrically or by way of hand.
