JJA36250 - Square D PowerPacT J-Frame 250A 3-Pole 600VAC 25kA I-Line Plug-In Molded Case Circuit Breaker, Thermal Magnetic Trip, UL/CSA/NOM/IEC/CE

Product Overview

The JJA36250 is a Square D PowerPacT J‑Frame molded case circuit breaker (MCCB) rated 250A, 3‑pole, 600 VAC with a 25 kA interrupting rating. It uses a thermal‑magnetic trip mechanism and is an I‑Line plug‑in design.

This SKU is factory‑original Square D equipment and is listed with UL, CSA, NOM, IEC and CE markings as indicated in the model designation.

Key Features

• Ampacity: 250 A; 3‑pole configuration for three‑phase systems
• Voltage rating: 600 VAC
• Interrupting rating: 25 kA
• Trip type: thermal‑magnetic (combined long‑time/short‑time protection)
• Form factor: PowerPacT J‑Frame I‑Line plug‑in molded case breaker

Function and protection

The JJA36250 provides overcurrent protection for three‑phase power circuits. Its thermal‑magnetic trip mechanism delivers both long‑time (thermal) protection for overloads and instantaneous (magnetic) protection for short‑circuit events.

• 3‑pole design protects all three phases simultaneously
• Combined thermal and magnetic trip characteristics for overload and short‑circuit protection
