SQUARE D HJA36100 Circuit Breaker, 100A, 3 Pole, 600VAC, 25KA, I-Line, Thermal Magnetic

Square D HJA36100 moulded case circuit breaker is used in industrial and commercial electrical distribution systems to safeguard electrical circuits and equipment from overcurrents and short circuits. This breaker has high interrupting capacity and reliable performance to ensure equipment safety, preventing damage due to excessive currents and maintaining uninterrupted power distribution.

Working Mechanism:

• Current passes through closed breaker contacts.
• Abnormal current exceeds set limit while overcurrent triggers magnetic trip coil.
• Magnetic field moves armature rapidly and the armature motion separates contacts.
• Contacts' separation breaks current path and rapid action protects system from damage.

Features:

• It occupies 4.5 inches of I-Line mounting space and has an interrupt rating of up to 25kA.
• This MCCB features 3 poles for effective circuit control and plug-on design for ease of installation.
• It offers thermal magnetic protection and performs long-time and instantaneous functions.
• This Square D 3-pole MCCB has a I-Line style plug-in connection for enhanced operations in adverse conditions.
• It features a snap-in terminal design for easy conversion between busbar and lug options.

Compatible Accessories:

• Square D QO Series Load Centers: These load centers are used in industrial and commercial applications to distribute electrical current. They work in conjunction with the brand's HJA series circuit breakers for increased protection against overcurrents and short circuits within electrical systems.
