Superior Safety and ComplianceEngineered with silver-plated copper contacts and exceeding IEC 60947-3 and IEC fire resistance standards, this isolator guarantees dependable circuit isolation for industrial and commercial settings. IP20 protection, RoHS compliance, and a padlock provision secure both users and systems.
Effortless Installation and OperationThe units DIN rail or panel mounting flexibility, spacious terminal accommodations (up to 70 mm), and ergonomic rotary handle streamline installation and user interaction. The handle can be locked in the OFF position for added operational safety. Maintenance-free design ensures long-lasting reliability.
Performance and DurabilitySupporting a mechanical life of 10,000 operations and compatible with a supply voltage up to 415V and current rating of 250A, this isolator excels under heavy-duty cycles. Its double-break contacts, high dielectric strength, and rapid response time (instantaneous operation) provide consistent, robust performance in demanding applications.
FAQs of 250A Isolator:
Q: How does the 250A 4-pole isolator ensure safe electrical isolation?
A: The isolator uses silver-plated copper contacts and a rotary handle mechanism to physically and securely break each pole of a 3-phase supply, preventing unintended current flow during maintenance or emergencies. Its padlockable OFF position enhances personnel safety by locking the device in an isolated state.
Q: What is the correct installation process for this isolator?
A: Installation can be done on a DIN rail or directly onto a panel. Ensure the cable size does not exceed 70 mm and tighten terminal screws to 3.5 Nm. The isolators standard dimensions (225 x 130 x 85 mm) make it suitable for most panel boards, and clear phase markings aid correct wiring.
Q: When should I use this isolator in my electrical system?
A: This isolator is recommended for use when a reliable and safe means is required to disconnect electrical circuits, especially in industrial or commercial applications. It is ideal during routine maintenance, emergency shutdowns, or when isolating specific loads for servicing.
Q: Where can this isolator be mounted?
A: The device is designed for installation within industrial or commercial electrical distribution panel boards and can be mounted on either DIN rails or panels, providing flexible integration into various system layouts.
Q: What benefits does the fire-resistant design and compliance offer?
A: Fire-resistant construction (in accordance with IEC standards) and RoHS compliance reduce risks in critical installations, supporting safer operations in high-demand environments. These features also help meet regulatory requirements for building and workplace safety.
Q: How does the rotary handle and padlock provision enhance usage and security?
A: The rotary handle allows smooth manual operation for circuit switching, while the padlock facility in the OFF position ensures only authorized personnel can re-energize circuits, minimizing accidental or unauthorized operation.
Q: What routine maintenance is required for this isolator?
A: This isolator is designed to be maintenance-free under normal operating conditions. Regular visual inspection to check for dust, debris, and secure terminals is recommended, but no routine internal maintenance is necessary.
