NewTrend · L+N switched voltage and current protector
Product overview
NewTrend PS8-13 provides true RMS voltage/current monitoring with adjustable overvoltage, undervoltage and overcurrent protection for AC 220V line-to-neutral circuits. Both L and N have disconnecting contacts, as shown in the original wiring diagrams. Select a 63A or 80A AC-1 version and factory upper- or lower-incoming wiring. The 54mm-wide DIN-rail protector displays voltage, current and fault status and automatically resets after fault recovery and the configured reset delay.

Operation
- Select the 63A or 80A AC-1 version and the U (upper incoming) or D (lower incoming) factory wiring configuration.
- Set overvoltage to OFF or 230-300V and undervoltage to 140-210V or OFF. Voltage-fault action delay is adjustable from 0.1-10s.
- Set the overcurrent threshold from 1A up to the selected rated current and the overcurrent delay within 2-600s. Power-up delay is 2-600s and reset delay is 2-900s.
- The original wiring diagrams show switching contacts in L and N. The front panel displays voltage and current and provides separate protection/output status indications.
- Hold M for 3s to enter settings and hold for 3s after changes to save. The decrease/power button supports manual output operation after settings and manual reset when automatic fault reset is disabled.
Typical applications
- Household-equipment circuits requiring abnormal-voltage and overcurrent protection
- DIN-rail distribution panels specifying switched L and N conductors with adjustable recovery timing

Original timing, L/N wiring, dimensions and no-isolation instruction
The factory expressly states that PS8-13 has no isolation function. Disconnect the upstream circuit breaker before maintenance. Follow the exact U or D incoming-line diagram and select the overcurrent threshold within the ordered current rating; coordinate separate circuit and short-circuit protection for the installation. Installation and wiring must be performed by qualified electricians.
