Product Overview

The Square D JDL36250 is a PowerPacT J series molded case circuit breaker rated 250 amps, 3‑pole, for use on 600 V systems. It uses a thermal‑magnetic trip mechanism and is UL listed with an 18 kAIC interrupting rating.

This SKU is configured as a feed‑thru breaker and is intended for power distribution applications where a 250A, 3P protective device with feed‑through capability and UL listing is required. Request a quote for pricing and availability.

Key Features

• 250 A continuous ampere rating; 3‑pole configuration for three‑phase circuits
• 600 V maximum system voltage rating
• Thermal‑magnetic trip for combined overload and short‑circuit protection
• 18 kAIC (kiloampere interrupting capacity)
• Feed‑thru design for downstream distribution
• UL listed

Function and basic purpose

The JDL36250 is a molded case circuit breaker from Square D’s PowerPacT J line designed to protect three‑phase electrical distribution circuits. It combines thermal (overload) protection with magnetic (short‑circuit) tripping to interrupt fault currents and help prevent equipment damage and wiring overheating.

• Protects three‑phase loads and feeder circuits at 250 A
• Intended for power distribution panels and switchboards where a feed‑through breaker is required

Electrical ratings and trip type

Use the JDL36250 where a 250 A, 3‑pole breaker with a 600 V maximum rating is required. The breaker uses a thermal‑magnetic trip that provides both overload and instantaneous fault protection. Its interrupting rating is 18 kAIC.

• Ampere rating: 250 A
• Poles: 3 (three‑pole)
• Maximum voltage: 600 V
• Trip type: Thermal‑magnetic
• Interrupting capacity: 18 kAIC

Feed‑through configuration

This SKU is specified as a feed‑thru breaker, allowing incoming power to continue downstream from the breaker to feed other devices or subpanels. Feed‑through breakers are typically used where distribution of power beyond the protected load is required while maintaining protection at the breaker location.

• Designed and labeled as feed‑thru
• Provides downstream distribution capability while functioning as a protective device

Listings and safety

The JDL36250 is UL listed. Use the breaker in installations that require UL listing and verify local codes and application requirements when specifying protective devices.

• UL listed

Selection and ordering

Confirm that the JDL36250’s electrical ratings and feed‑through configuration match your application before ordering. For pricing and availability, request a quote.

• Verify system voltage (600 V max) and required interrupting rating (18 kAIC)
• Confirm 250 A, 3‑pole capacity and feed‑through needs
• Provide model number (JDL36250) and required quantity when requesting a quote

Before You Order

Confirm the model number and quantity required before ordering. Ensure the breaker’s voltage, ampere rating, interrupting capacity, pole count, and feed‑through configuration match your system and local code requirements.

• Provide the exact SKU: JDL36250 when requesting a quote
• Verify electrical compatibility: 250 A, 3‑pole, 600 V max, 18 kAIC
• Confirm feed‑through capability is suitable for your panel or distribution layout
