Allen Bradley 700-CPM Bulletin 700 Master Contact Cartridge

Product Overview

The Allen Bradley 700-CPM represents the high-capacity "Master" tier of contact cartridges engineered for the Bulletin 700P heavy-duty relay series. This component provides superior switching capability for demanding control circuits, handling significantly higher inrush currents and thermal loads than standard-duty cartridges. It serves as a field-replaceable and convertible interface, allowing for seamless adaptation between Normally Open (NO) and Normally Closed (NC) logic. We supply this unit as 100% Brand New and Factory Original, ensuring your safety interlocks and control sequences meet OEM specifications.

Technical Specifications

Engineering Advantages

• Logic Flexibility on Demand: The 700-CPM features a reversible design. Technicians change the contact state from Normally Open to Normally Closed simply by rotating the cartridge 180 degrees before installation. This eliminates the need to stock multiple part numbers for different logic requirements.

• High-Inrush Capability: The "Master" designation signifies a robust 20A rating. This cartridge handles the massive surge currents associated with large solenoid valves, magnetic starters, and industrial sirens that would otherwise weld or pit standard 10A contacts.

• Industrial-Grade Dielectric Integrity: The cartridge housing withstands up to 600V AC/DC. This high insulation rating prevents cross-phase arcing and maintains circuit isolation even in high-voltage control cabinets subjected to transient spikes.

• Tool-Free Maintenance: The snap-in architecture permits rapid replacement without dismantling the relay base. This design significantly reduces Mean Time to Repair (MTTR) during critical process outages.

• Mechanical Synchronization: The internal bridge mechanism ensures precise, simultaneous actuation across all poles. This synchronization prevents "race conditions" in complex hard-wired logic arrays.

FAQs

• How do I distinguish a 700-CPM from a standard 700-CP1 cartridge?

  The 700-CPM features a distinct "Master" marking and utilizes larger contact surface areas. You must use the Master version whenever the connected load exceeds 10A or requires a 600V rating in a heavy-duty Bulletin 700P frame.

• Can I mix Master and Standard contacts in a single relay?

  Yes. Bulletin 700P relays support a hybrid configuration. You can install 700-CPM Master cartridges in high-load poles and standard cartridges in low-power logic poles within the same relay footprint to optimize panel space.

• Is this a brand new factory unit or surplus?

  We guarantee this 700-CPM is 100% Brand New in its original Allen Bradley packaging. We do not sell "new-old-stock" or refurbished contacts, as worn or oxidized contact points compromise the reliability of industrial safety systems.

• What is the correct way to convert from NO to NC?

  First, ensure you de-energize the relay. Remove the cartridge, flip it so the desired symbol (NO or NC) faces the front of the relay, and snap it back into the pole slot. The mechanical actuator in the relay base automatically aligns with the internal bridge.
