JT3070T - 70Amp Trip Unit

JT3070T - 70Amp Trip Unit

The Eaton JT3070T is a 70A, three-pole thermal-magnetic trip unit for Series C molded-case circuit breaker equipment, using a J-frame and JT circuit breaker type. For replacement work, those identifiers are worth checking together rather than relying on amperage alone. The JT3070T is built to last and is suited to form, fit, and functional replacement situations where your existing equipment specifically calls for this 70A Series C J-frame trip-unit configuration. Because this is a trip unit accessory rather than a complete circuit breaker, confirm the breaker type, frame, trip type, pole count, and current rating before installation.

Key Features and Benefits

• 70A amperage rating for applications requiring this specific trip-unit rating.
• Three-pole configuration for compatible three-pole Series C equipment.
• Thermal-magnetic trip unit provides the specified trip functionality for the compatible breaker assembly.
• T185 trip type provides a specific identifier when matching an existing unit.
• Intended for JT circuit breaker type and J-frame compatibility.
• Part of the Eaton Series C product family.
• UL Listed according to the manufacturer's specifications.

Material Compliance and Certifications

The Eaton JT3070T is UL Listed according to the supplied manufacturer specifications. Eaton lists the product's broader compliance information as Contact Manufacturer, so additional compliance claims should not be assumed without verification.

Where It Works Best

The JT3070T is best suited to compatible existing and legacy Eaton Series C J-frame molded case circuit breaker equipment requiring a 70A, three-pole, T185 thermal-magnetic trip unit for a JT circuit breaker type. Its catalog number, frame designation, trip type, amperage, and pole count provide concrete details to confirm the correct replacement.

This product is a trip unit accessory, not a complete molded case circuit breaker. Before installation, verify the JT breaker type, J frame, 70A rating, three-pole arrangement, T185 trip designation, dimensions, and all other equipment requirements against the existing assembly.
