Albright SW560A-38M 24V Magnetically Latched Contactor (INT.)
Albright International SW560A-38M is a 24 Volt single-pole, single-throw (SPST) magnetically latched solenoid contactor, intermittent rated, supplied with auxiliary microswitch.
The SW560A is designed for telecommunications and power distribution applications where an uninterrupted current load is switched. These contactors are primarily intended for Direct Current (DC) loads but may also be used with Alternating Current (AC).
Key Features
- 24V coil voltage
- Single-pole, single-throw (SPST)
- Magnetically latched design
- Intermittent duty (INT.)
- Auxiliary microswitch fitted
- Double-breaking main contacts
- Silver-alloy contact tips – weld-resistant and high conductivity
- Silver-plated main contacts (standard)
- Special operating knob and extension fitted
- Yellow warning label fitted
About Intermittent (INT.) SW560A Solenoids
Intermittent contactors are typically used for hydraulic functions on vehicles. They make and break faster than continuous duty solenoids and are not recommended for prolonged contact periods.
Magnetic Latching Function
The contact position is secured using a permanent magnet within the assembly. The coil requires a pulse to close the contacts and a reverse-polarity pulse to open them. Once operated, the contactor remains in its last energised state without requiring continuous power.
Please note: magnetically latched contactors are not failsafe devices.
Mounting Information
The SW560A is a compact contactor that can be busbar-mounted vertically or horizontally. If mounted vertically, the coil should be positioned at the bottom.
Auxiliary Microswitch
This version includes an auxiliary microswitch mounted on the top cover. The auxiliary contact connection is triggered by coil energising.
Uninterrupted Current Applications
Suitable for applications with no or infrequent load switching requirements, helping to maintain lower contact resistance over time.
