JBA2 (LA2) Series Air Delay Head
Type and Signification
① Air delay head
② Design Number (2, 3)
③ Delay range: 0 for 01-3S, 2 for 01-30A, 4 for 10-180S
Application Range
JBA2 series air delay head is mainly used for AC 50HZ or 60HZ, AC-15 use category, rated working voltage is AC380Mrated current to 0.95A or DC-13 use category, rated working voltage is DC220Mrated current to 0.15A control line, as delay control.
The product is connected to JBC1 series AC contactor or JBC4 contactor relay. The contacts of contactor or relay support the connector part of the pulling delay head, which produces the corresponding delay effect. There are two kinds of delay, one is power delay and the other is power cut delay. The delay is connected or disconnected in the control circuit.
This series of products meet GB14048.5 and IEC 60947-5-1 standards.
