Selectronic 250A Current Transformer for use with SP PRO - ELCT250/5

Overview

The Selectronic 250 A Current Transformer is an essential accessory for SP PRO inverter systems requiring control and monitoring of AC source supplies that exceed the capacity of the inverter’s internal wiring and contactor.

By using an external contactor and current transformer in place of the internal components, SP PRO systems can safely integrate and manage very large AC sources. This configuration enables advanced system designs for commercial and industrial energy applications.

Key Features

High-Current AC Source Integration

• Allows SP PRO systems to control AC sources larger than internal limits
• Works in conjunction with an external contactor
• Replaces the internal SP PRO contactor and CT functionality

Extended System Capacity

• Supports AC source supplies up to 1000 A with supported firmware
• Limited to 250 A for firmware revision 8.0 or earlier
• Ideal for large generators, grid connections, or commercial AC sources

SP PRO Compatibility

• Designed for use with all Selectronic SP PRO inverter products
• Enables advanced system configurations beyond standard inverter limits
