The Thermally Protected Advantage

Superior by Design

The 1202-P’s built-in thermal element responds to prolonged high-energy surges by activating when excessive heating is detected.
Provides robust surge-handling capability (Nominal Discharge Current (I_n) 20 kA and Maximum Discharge Current (I_max) 50 kA) to satisfy broader and stricter protection standards.

Thermal Protection Advantages

When the thermal element activates, it disconnects itself from the circuit.
This prevents sustained overheating and potential thermal runaway, enhancing the safety and reliability of the surge protection.

1202-P SPD Usage & Installation

Wiring Configurations for Bourns® 1202 Series Type 1 SPDs

Per the National Electrical Code® (NEC) and ANSI/UL 1449, SPDs are designated as follows:

Type 1: Permanently connected, intended for installation between the secondary of the service transformer and the line side of the service disconnect overcurrent device (service equipment). Their main purpose is to protect insulation levels of the electrical system against external surges caused by lightning or utility capacitor bank switching.

Type 2: Permanently connected, intended for installation on the load side of the service disconnect overcurrent device (service equipment), including brand panel locations. Their main purpose is to protect the sensitive electronics and microprocessor based loads against residual lightning energy, motor generated surges and other internally generated surge events.
