Technical Description
The Kayama KRPSS63 Digital Overvoltage and Undervoltage Protection Relay is designed to monitor the electrical supply voltage and provide automatic operation when the monitored voltage moves outside the configured limits.
The unit has a stated nominal supply of 220 VAC, frequency of 50/60 Hz and stated maximum current of up to 63 A.
Its digital display allows the monitored voltage to be viewed and assists with configuration of the parameters available on the device.
The KRPSS63 also features a stated timing range of 2 to 600 seconds.
Technical Characteristics
- Brand: Kayama
- Model: KRPSS63
- Type: Digital overvoltage and undervoltage protection relay
- Nominal voltage: 220 VAC
- Frequency: 50/60 Hz
- Stated maximum current: up to 63 A
- Display: digital
- Parameters: configurable
- Stated time delay: 2 to 600 seconds

Voltage Monitoring
The KRPSS63 monitors the electrical supply and allows the circuit to be disconnected when voltage conditions fall outside configured parameters.
This function assists in protecting connected equipment against abnormal supply-voltage conditions.
Overvoltage Protection
The overvoltage function allows operation when the monitored voltage exceeds the configured upper threshold.
The exact setting should be selected according to the characteristics of the installation and connected equipment.
Undervoltage Protection
The device can also operate when the voltage falls below the configured minimum threshold.
The setting should be selected according to the actual requirements of the installation.
Digital Display
The digital display allows operating information and monitored voltage to be viewed.
It facilitates voltage monitoring, parameter configuration, installation adjustments and periodic inspection.
Configurable Parameters
The KRPSS63 allows parameters associated with voltage monitoring and protection to be configured.
Settings related to operating thresholds and delay time should be adjusted according to the installation.
2 to 600 Second Timing Range
The stated timing range is 2 to 600 seconds.
This feature allows a time interval to be incorporated into the operating logic according to the selected configuration.
Maximum Current up to 63 A
The stated maximum current is up to 63 A.
Actual application must also consider load current, inrush current, load characteristics, conductor sizing, protection devices and operating conditions.
When direct load switching is not suitable, a properly sized external contactor may be required.
DIN Rail Mounting
The KRPSS63 is specified for DIN rail mounting, facilitating installation in electrical distribution and control panels.
Electrical Installation
Before installation, verify nominal voltage, network frequency, load current, starting current, conductor sizing, electrical protection, voltage settings and time-delay configuration.
All wiring must be carried out with the circuit de-energized.
Complementary Protection
The KRPSS63 is intended to monitor and protect against overvoltage and undervoltage conditions.
It does not replace circuit breakers, fuses, surge protection devices, residual-current devices, grounding or specific motor protection.
KRPSS63 vs. Surge Protection Device
The KRPSS63 should not be confused with a surge protection device (SPD).
The KRPSS63 monitors the supply voltage according to configured thresholds, while an SPD is designed to protect against transient voltage surges.
