Description
A50-30-11 1SBL351001R8011 contactors are mainly used for controlling 3-phase motors and generally for controlling power circuits up to 690 V AC / 1000 V AC or 220 V DC. The contactors can also be used for many other applications such as isolation, capacitor switching, lighting. The A... series 1-stack 3-pole contactors are of the block type design.
- Main poles and auxiliary contact blocks: 3 main poles and 2 built-in auxiliary contacts, front and side-mounted add-on auxiliary contact blocks
- Control circuit: AC operated with laminated magnet circuit
- Accessories: a wide range of accessories is available.
Applications
Injection Molding Plant: Used for frequent starts of heater circuits and motor pump sets.
Water Treatment Plant: Remotely controls the start and stop of sewage pumps and booster pumps.
Chemical Plant: Drives reactor agitator motors and ventilation/exhaust systems.
Cement Plant: Integrated into conveyor belt control cabinets to handle switching of highly inductive loads.
Textile Plant: Used for main power distribution and overload protection linkage on large looms.
Competitive Advantage
Highly Compact Design: Smaller size for the same 50A load capacity, saving rack space.
Integrated Auxiliary Contacts: Standard configuration includes 1 NO + 1 NC auxiliary contacts, eliminating the need for additional installation modules and reducing costs.
Global Certifications: Compliant with multiple international standards such as IEC, UL, and CSA, facilitating compatibility with exported equipment.
FAQ
Q: Can the A50-30-11 1SBL351001R8011 module be controlled with DC 24V?
A: No, this model's coil is driven by 220V AC. DC control requires the NL series.
Q: What if there aren't enough auxiliary contacts in the A50-30-11 1SBL351001R8011?
A: A CA5 series front-mounted auxiliary contact block can be added to the top.
Q: What is the maximum power motor the A50-30-11 1SBL351001R8011 can control?
A: Under standard 400V voltage, it is recommended to control motors up to 22 kW.
Q: Can a broken contact in the A50-30-11 1SBL351001R8011 be replaced individually?
A: The A50 series supports replacing the contact kit; the entire contactor does not need to be replaced.
Q: Can the A50-30-11 1SBL351001R8011 be installed horizontally?
A: Vertical installation is recommended. If horizontal installation is necessary, performance may be slightly affected.
