2 (Option Package 2): Adds enhanced safety protections (ground fault, stalled rotor, thermistor winding overtemperature), power/energy metering metrics, and a second contactor control line.
240: 240 Volts AC nominal control voltage supply.

Physical Specifications
Form Factor: Flush panel-mount industrial protective housing.
Dimensions: Approximately 17.5 cm Width x 10.5 cm Height x 16.0 cm Depth (Designed to seamlessly fit inside tight, standard-sized MCC buckets).
Weight: Approximately 3.0 kg to 4.0 kg (6.6 lbs to 8.8 lbs) depending on internal terminal revisions.
Commercial & Logistics Data
Country of Origin: Canada (or United States, depending on original manufacturing batch)
Customs Tariff Number (HS Code): 8536490000 or 85371091 (Electrical relays or electronic programmable control units for electrical motor protection)
Electrical & Operational Specifications
Control Power Supply Input: 240 V AC nominal (±10% operational allowance, 50/60 Hz frequency line).
Relay Contact Capacity: Integrated electromechanical control output relays rated up to 10A at 250V AC resistive / 5A at 250V AC inductive loads.
Communication Interface: Native RS-485 serial communication terminal port supporting Modbus RTU protocol with data transmission rates ranging from 1,200 to 19,200 bps.
Software Tool Compatibility: Fully compatible with GE’s EnerVista software suites for streamlined remote commissioning, configuration archiving, and parameter adjustments.

Environmental Limits
Operating Ambient Temperature: 0°C to 60°C (32°F to 140°F)
Storage Temperature Range: -30°C to 80°C (-22°F to 176°F)
Relative Humidity Support: 5% to 95% RH (non-condensing atmospheric conditions).
Front Panel Faceplate Protection: Compliant with NEMA Type 12 / IP53 moisture and dust sealing standards when properly flush-mounted into a cabinet door.
Key Features and Characteristics
All-In-One Protection Suite: Provides a highly reliable motor thermal model alongside protections for phase current unbalance, ground fault (50G/51G), mechanical jam/stalled rotor, undercurrent, phase loss, and contactor failure.
Flexible Smart Starter Control: Features built-in preconfigured control logic loops supporting multiple standard starter types, including full-voltage non-reversing/reversing, wye-delta, two-speed, and variable frequency drive (VFD) bypass topologies.
Winding Overtemperature Sensing: Equipped with a dedicated hardware thermistor input channel that interfaces with PTC or NTC sensors embedded inside the motor windings to capture insulation overheating directly.
Power and Energy Metering: Utilizes a single-phase voltage transformer input to calculate, track, and display real-time power analytics such as kilowatts (kW) and cumulative kilowatt-hours (kWh).
Automatic Undervoltage Recovery: Implements customizable undervoltage auto-restart timing routines to automatically step through safe, staged equipment reboots following transient plant-wide power dips.
Local User Interface (HMI): Built with an integrated 40-character (20 x 2 alphanumeric) backlit LCD screen, localized programming keypad buttons, and 11 distinct LED indicators for rapid visual tracking of motor and relay trip statuses.
